KeepFiringFor time.Duration
Labels map[string]string
Annotations map[string]string
GroupID uint64
GroupName string
EvalInterval time.Duration
Debug bool
// contains filtered or unexported fields
}
AlertingRule is basic alert entity

func NewAlertingRule(qb datasource.QuerierBuilder, group *Group, cfg config.Rule) *AlertingRule
NewAlertingRule creates a new AlertingRule
func (*AlertingRule) GetAlert ¶
func (ar *AlertingRule) GetAlert(id uint64) *notifier.Alert
GetAlert returns alert if id exists
func (*AlertingRule) GetAlerts ¶
func (ar *AlertingRule) GetAlerts() []*notifier.Alert
GetAlerts returns active alerts of rule
func (*AlertingRule) ID ¶
func (ar *AlertingRule) ID() uint64
ID returns unique Rule ID within the parent Group.
func (*AlertingRule) String ¶
func (ar *AlertingRule) String() string
String implements Stringer interface
type Group ¶
type Group struct {
Name string
File string
Rules []Rule
Type config.Type
Interval time.Duration
EvalOffset *time.Duration
// EvalDelay will adjust timestamp for rule evaluation requests to compensate intentional query delay from datasource.
// see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5155
EvalDelay *time.Duration
Limit int
Concurrency int
Checksum string
LastEvaluation time.Time
Labels map[string]string

func NewGroup ¶
func NewGroup(cfg config.Group, qb datasource.QuerierBuilder, defaultInterval time.Duration, labels map[string]string) *Group
NewGroup returns a new group
func (*Group) Close ¶
func (g *Group) Close()
Close stops the group and it's rules, unregisters group metrics
func (*Group) ExecOnce ¶
func (g *Group) ExecOnce(ctx context.Context, nts func() []notifier.Notifier, rw remotewrite.RWClient, evalTS time.Time) chan error
ExecOnce evaluates all the rules under group for once with given timestamp.
func (*Group) InterruptEval ¶
func (g *Group) InterruptEval()
InterruptEval interrupts in-flight rules evaluations within the group. It is expected that g.evalCancel will be repopulated after the call.
func (*Group) Replay ¶
func (g *Group) Replay(start, end time.Time, rw remotewrite.RWClient, maxDataPoint, replayRuleRetryAttempts int, replayDelay time.Duration, disableProgressBar bool) int
Replay performs group replay
func (*Group) Start ¶
func (g *Group) Start(ctx context.Context, nts func() []notifier.Notifier, rw remotewrite.RWClient, rr datasource.QuerierBuilder)
Start starts group's evaluation
func (*Group) UpdateWith ¶
UpdateWith inserts new group to updateCh
type RecordingRule ¶
type RecordingRule struct {
Type config.Type
RuleID uint64
Name string
Expr string
Labels map[string]string
GroupID uint64
// contains filtered or unexported fields
}
RecordingRule is a Rule that supposed to evaluate configured Expression and return TimeSeries as result.
func NewRecordingRule ¶
func NewRecordingRule(qb datasource.QuerierBuilder, group *Group, cfg config.Rule) *RecordingRule
NewRecordingRule creates a new RecordingRule
func (*RecordingRule) ID ¶
func (rr *RecordingRule) ID() uint64
ID returns unique Rule ID within the parent Group.
func (*RecordingRule) String ¶
func (rr *RecordingRule) String() string
String implements Stringer interface
type Rule ¶
type Rule interface {
// ID returns unique ID that may be used for
// identifying this Rule among others.
ID() uint64
// contains filtered or unexported methods
}
Rule represents alerting or recording rule that has unique ID, can be Executed and updated with other Rule.
type StateEntry ¶
type StateEntry struct {
// stores last moment of time rule.Exec was called
Time time.Time
// stores the timesteamp with which rule.Exec was called
At time.Time
// stores the duration of the last rule.Exec call
Duration time.Duration
// stores last error that happened in Exec func
// resets on every successful Exec
// may be used as Health ruleState
Err error
// stores the number of samples returned during
// the last evaluation
Samples int
// stores the number of time series fetched during
// the last evaluation.
// Is supported by VictoriaMetrics only, starting from v1.90.0
// If seriesFetched == nil, then this attribute was missing in
// datasource response (unsupported).
SeriesFetched *int
// stores the curl command reflecting the HTTP request used during rule.Exec
Curl string
}
StateEntry stores rule's execution states
func GetAllRuleState ¶
func GetAllRuleState(r Rule) []StateEntry
GetAllRuleState returns rule entire stateEntries
func GetLastEntry ¶
func GetLastEntry(r Rule) StateEntry
GetLastEntry returns latest stateEntry of rule
